What is this Steel shape?
(OP)
I was inspecting a prefab metal building the other day and came across a mezzanine floor that was framed with 12" deep x 2" wide "C" shapes. These are not metal stud (cold formed), and they aren't in the AISC steel book. They are hot rolled (?) and are about 3/16" thick. I have attached a photo. what is the generic category of this type of steel shape and where would I look for design specification?
I have seen this "type" of steel most commonly used on metal building girts. I saw some the other day used in a precast hybrid concrete panel (3" thick panel with 6" studs at 24" on center).
I just have never used this stuff and would like to start.

I think you are describing 'stair channels'.

They could be a break formed section, depending upon their length , by the PEMB manuf’er., in their own shop. They could be a proprietary rolled shape done for the PEMB manuf’er., by a mill. A section that they use fairly often for several different things, and in sufficient quantity that they can afford the set-up costs for a mill run. There are many proprietary sections out there. They pay for the special set of rolls or combine several existing rolls in the mills inventory; then they have to pay for set-up and buy in sufficient quantity to induce the mill to do the special rolling for them. Maybe they get a special price from one supplier on 3/16" coil stock, and then can design around a constant thickness section. I suspect that in that thickness, that stock could be slit and then cold rolled in a secondary processing shop. I think you should try to get the info. you need directly from the PEMB manuf’er., because you will at least need the thickness, other dimensions, and a mat’l. spec. and properties.

therefore 7ga (alomst 3/16") CEE seems to be what you have. Probably not off the shelf item.
